THREAD TIER.

Application filed September 22, 1924. Serial No. 739,115.

My invention relates to an improvement in thread tiers.

The object of my invention is to provide a device of the character named which can be used in stores or offices, and which can be conveniently held and operated by one hand of the operator, leaving the other hand free to manipulate the threads to be tied together.

Another object of my invention is to provide a device of few and simple parts capable of being easily formed and assembled so that it may be manufactured and sold at a comparatively small cost.

My device may be hung from the ceiling of a store or it may be placed on a pencil or other suitable handle, according to the purpose and size of the tier.

In the accompanying drawings:

Fig. 1 is a side elevation of my improved device;

Fig. 2 is an enlarged vertical sectional view of the same;

Fig. 3 is a section on line 33 of Fig. 2;

Fig. 4c is a vertical sectional view through the head; and

Figs. 5, 6, 7 and 8 are views showing successively different stages in the tying operation. 30 My improved thread tier preferably'consists in a hollow casing or neck 1 having a head 2 at one end thereof. This casing may be cast in the desired shape or it may be made of sheet metal and bent into the form of a housing.

A lever 3 is preferably curved throughout the major portion of its length, as shown in Fig. 2 in full lines, and in dotted lines in Figs. 1 and 5 to 8 inclusive, to conform approximately to the curvature of the edge of the head within which it normally lies, and one end of this lever extends radially inwardly to a point where it is pivoted to the head 1 by a screw or pin 4, around which it swings as a center of oscillation.

A pinion 5 is mounted on the pin 4 and secured to the lever 3 for turning the latter. A rack bar 6 within the casing has its teeth meshing with the teeth of the pinion 5. The rack-bar extends rearwardly in the casing and has its end 7 bent or turned outwardly and extending through a slot 8 in the casing.

A handle or thumb piece 9 is provided at the end of the part 7 of the rack bar and exterlorly of the casing for moving the rack bar 6 and turning the pinion 5 and lever 3,

all of which is clearlv shown in Figs. 1, 2 and 3. A spring 10 is connected with the rack bar 6 for holdieg it in its rearward position, as shown in Fig. 2.

A handle 11 may be screw-threaded or otherwise secured to the neck or casing 1,

and a screw eye 12 is secured to the handle a hook to receive and hold the threads to.

be tied, they being wedged therein. A slot 14: is provided in the back of the head 2 forming a hook and a knife 15 is secured within the hook across the inner end of this.

slot as shown in Figures 1 and 2 for severing the threads at the proper time.

In the operation, the threads of which only one is shown for convenience, are first drawn across the top of the head as shown in Fig. 5. The handle 9 is pushed forward swinging the lever 3 around into the position shown in Figure 6 until the threads are caught and wedged in the recess 13 of the hook. The handle 9 is again drawn backwardly until the lever resumes its normal position as shown in Figure 7 the threads having been carried around or through the head by the lever 3 to form the loop 1'7, whereupon owing to the peculiar shape of the edge of the head, the loop 17 slides off over the head as shown in Figure 8, thereby completing the knot as the threads are drawn tight. Any surplus thread ends may be drawn through the slot 1 1 and cut by the knife 15.

Thus a very simple manner and an equally simple mechanism are provided for tying two or more threads together. It will be obvious that various slight changes may be made without departing from the scope of my invention, the form shown and described being typical and not necessarily the only form the invention may take.

I claim:

1, A thread tier including a head, a lever pivoted thereto, gearing for actuating said lever, and means for slidablyoperati-ng said gearing.

2. A thread tier including a casing, a head at one end thereof, a lever pivoted to the head and having a recess for receiving the threads, a gear connected with the lever, and a rack bar actuating the gear and lever for drawing the ends of the threads around the head forming a loop in the threads.

3. A thread'tier including'a casing, a head, a lever pivoted thereto, and having a recess for receiving threads, a gear connected with the lever, a rack-bar for actuating the gear and lever, and manually controlled means for operating said rack-bar.

4'. Ath'read tier including a casing, having anopening therein, a head, a lever pivotedto' the head, a. gear connected with the lever, a rack-bar foractuating the gear and lever,tand' a handle extendingthrough the openingin' the casing and connected with the rack-bar for operating said bar and gear.

A threacl'=tier including a casing, having an opening therein, a head, a lever pivoted to the head, a gearconnected with the lever, a rack-bar for actuating the gear and lever, a handle extending through the opening in the casing and connected with the v rack-bar for operatingsaid bar and gear, and

a-spring connected with the casing and rack bar for normally tending to hold said rackbar in its rearward position.

6. A thread tier including a casing having 1,ea1,ese

an opening therein, a head, a lever pivoted to the head, gearing for actuating the lever, and a handle extending through the opening in the casing and connected with the gear ing for slidabiy operating said gearing and lever.

' 7. A thread tier including a casing, a head at one end thereof, a lever pivoted to the head and having a recess for receiving the threads, a gear connected with the lever, a rack bar having one end bent outwardly and extending through a slot in the casing and having a handle on the end thereof in position to be actuated for rotating the lever,

.8. A thread tier including a head having a notch at one edge, alever pivoted in the head having a hook at the free end and a slot curved inwardly from the hook around the pivot, in position to clear the inner ends ot said notch while the hooked lever is closing the outer end thereof, means forspring ing. the leverin one direction, and means for returningit to its normal position in the formation oi a knot.

9. A device of the character described including a head, a curved lever pivoted therein and provided with a hook at the freeend, thehead having a cut-away portion at one edge within the radius of the travel of the hook, whereby to provide space for the thread to drop in the path of the hook in thetying of the knot.

In testimony whereof I affix my signature.
